David Arquette: Courteney Cox and I 'not back together'

Just so we're clear,
David Arquette would like the world -- or at least his 100,123 Twitter followers -- to know he and estranged wife
Courteney Cox are still separated despite having spent some recent quality time together.

Arquette
tweeted the FYI on Thursday (June 2) -- apparently the fact that the couple spent Memorial Day together with daughter Coco sparked rumors of a reconciliation. Not so according to Arquette:

The pair separated in October 2010 after 11 years of marriage. In April, first Arquette, then Cox spilled about their sex life to Howard Stern on his live satellite radio show. Arquette told Stern about a Disney World visit on which Cox refused him sex. Cox responded by doing a little of her own over-sharing, telling Stern, ""This is one of our problems in our relationship. Whenever I would need consoling from David, he could not literally put his arm around me for one second without completely getting a boner."
